Abstract

 

  The area understudy was surveyed using seismic refraction techniques as an available tool for engineering purposes. Eight seismic profiles for either P and S-waves had been chosen and carried out by the use of five impacts (center, normal, reverse, between geophones 6-7 and 18-19), in  order to delineate layers thicknesses and depth of water table underlying such a hostel complex site inside Basrah University, southern Iraq. Dynamic elastic modulii were also calculated depending upon the velocities of 

P and S-waves of these layers and its densities.

 

  Accordingly, three shallow subsurface soil layers were found. Their mean thicknesses are ranged between (2.15-2.45) m, (17.65-18.4) m below ground surface for the top and first layers respectively. On the other hand, mean water table seems to be at (2.3) m depth and the mean dynamic elastic constants are ranged between {κ= (0.194-7.352×103) Mpa, 

μ= (0.145-2.994×103) Mpa, E= (0.364-7.385×103) Mpa, λ= (0.092-5.764×103) Mpa, and, σ= (0.19-0.35)}.
